SHANGHAI and HONG KONG, Dec. 16, 2025 /PRNewswire/ -- Antengene Corporation Limited ( "Antengene", SEHK: 6996.HK), a leading innovative, commercial-stage global biotech company dedicated to discovering, developing and commercializing first-in-class and/or best-in-class medicines for autoimmune disease, solid tumors and hematological malignancies indications, today announced that the Malaysian National Pharmaceutical Regulatory Agency has approved a supplemental New Drug Application (sNDA) for XPOVIO® (selinexor) for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after at least 2 lines of systemic therapy, who are ineligible for autologous stem cell transplant. With this recent approval, XPOVIO® has further expanded its portfolio of approved indications in Malaysia, bringing the total to three indications across multiple myeloma (MM) and DLBCL, two major therapeutic areas in hematology. Prior to this, XPOVIO® was approved in Malaysia for two indications, including in combination with bortezomib and dexamethasone for the treatment of adult patients with MM who have received at least one prior therapy; and in combination with dexamethasone for the treatment of adult patients with MM who have received at least four prior therapies and whose disease is refractory to at least two proteasome inhibitors, two immunomodulatory agents and an anti-CD38 monoclonal antibody, and who have demonstrated disease progression on the last therapy. The latest indication expansion into DLBCL will allow XPOVIO® to benefit a broader population of patients, offering new hope and a meaningful treatment option for patients and families who have been urgently seeking effective therapies. With a novel mechanism of action, XPOVIO® is the world's first approved orally-available, selective XPO1 inhibitor, which has already been approved in ten countries and regions in APAC, and has been included in the national insurance schemes in five of these markets (the mainland of China, Taiwan market, Australia, Singapore and South Korea). Moving forward, XPOVIO® is expected to receive public insurance coverage in more APAC markets.

Eli Lilly’s retatrutide exceeds expectations in Phase III, capping off a sparkling 2025 for the obesity titan; an internal FDA safety review finds no confirmed pediatric deaths caused by COVID-19 vaccines, and Commissioner Marty Makary says no black box warning will be attached to the shots; and BioSpace looks at six biotechs that could be pharma’s next buy. > Listen on Spotify > Listen on Apple Products > Listen on Amazon Music > Listen on iHeart Eli Lilly is wrapping up 2025 with record-breaking weight loss in a late-stage trial for its triple hormone receptor agonist retatrutide . Results from the Phase III TRIUMPH-4 trial exceeded analyst expectations, leading BMO Capital markets to cleverly dub it “a true TRIUMPH.” Also in the weight loss arena, Zealand Pharma inked a deal with China’s OTR Therapeutics worth up to $2.5 billion to collaborate on next-gen drugs for obesity and other metabolic diseases, and Rhythm Pharmaceuticals awaits a Dec. 20 FDA verdict for Imcivree in hypothalamic obesity. Turning to the FDA, reports broke late last week that the agency was considering slapping a black box label—its strictest warning—on COVID-19 vaccines. Commissioner Marty Makary denied those reports on Monday, stating on Bloomberg TV that the FDA has “no plans” to make such a move. This follows an internal memo from Vinay Prasad leaked over Thanksgiving in which the CBER director claimed that “at least” 10 children have died “because of” COVID-19 vaccines. An internal safety review published last week refuted this conclusion, instead concluding that between zero and seven deaths could be linked to the shots. Pfizer CEO Albert Bourla , for one, is tired of the recent rhetoric from HHS on vaccines and hopes they are “an anomaly” that will be corrected soon. With strong words about the administration’s sentiment on vaccines, Bourla prominsed Pfizer’s continued investment in vaccines despite declining revenue. Pfizer this week lowered its 2026 guidance to $62.5 billion in revenue, missing analyst consensus. Clinical research 5 of 2025’s Defining Clinical Wins In the midst of regulatory and political upheaval, biopharma’s R&D engine kept running, churning out highs and lows in equal parts. Here are some of this year’s most glorious clinical trial victories. December 15, 2025 · 9 min read · Tristan Manalac The FDA has also granted several approvals in the past week, to Amgen , Milestone Pharmaceuticals and AstraZeneca and Daiichi Sankyo . USAntibiotics also snagged a greenlight, for Augmentin XR , the first approval to be given under the agency’s new Commissioner’s National Priority Voucher (CNPV) program. Also this week, Johnson & Johnson scored a CNPV ticket—without even having to apply—for its investigational combo of Tecvayli plus Darzalex for relapsed or refractory multiple myeloma after the FDA was impressed by Phase III data. In ClinicaSpace this week, we highlighted 5 of 2025’s Defining Clinical Wins and The 5 Most Painful Clinical Trial Failures of 2025 . This past week provided a few more on each front. In the winner’s circle, Immunome’s desmoid tumor drug and and Kyverna’s CAR T for stiff person syndrome both aced pivotal trials, while Sanofi’s MS drug tolebrutinib and Gilead and Arcus’ TIGIT therapy domvanalimab each failed Phase III tests. And in BioPharm Executive, we highlight 6 Biotechs That Could Be Big Pharma’s Next M&A Target , and more M&A predictions for 2026.
